Imagine it wasn't wget, but a tool you'd never used before and you didn't know what the arguments meant. All those options are poorly defined. Also, it's confusing how filetypes switch from checkboxes to a listbox.
Trying to cram everything into one panel has left us with nothing but the controls and very little space for information.
Also, even if you wanted that layout, the alignments are terrible and the use of frames is arbitrary and inconsistent.
If I were in that situation, and I find I often am, my choice is to go and read the manual. I think this comes from years of reading man pages for command line tools, but the first step I feel should always be to read the instructions.
